The Callisto Protocol EU Steam Altergift

A brutal survival horror set on Jupiter's dead moon

The Callisto Protocol is a narrative-driven, third-person survival horror game set 300 years in the future. Players take on the role of Jacob Lee, an inmate at Black Iron Prison, a maximum-security penitentiary on Callisto, Jupiter's moon. When the prisoners begin transforming into monstrous creatures, Jacob must fight his way through the chaos to escape, uncovering the dark secrets of the United Jupiter Company along the way.

Combat blends close-quarters brutality with ranged shooting, including a gravity weapon once used by the prison's guards. Jacob scavenges for new weapons, gear and abilities as the creatures around him evolve, forcing constant adaptation to survive Callisto's horrors.

Developed by Striking Distance Studios and published by Krafton, this is a story rich title that sits firmly within the horror games and action games genres, with plenty for fans of adventure games and story-rich games as well.
